SAW-SET.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed March 2, 1914. Serial No. 821,975.

To all whom it may concern:

Be it known that 1, CHARLES E. MILLER, a citizen of the United States ofAmerica, and resident of Bellingham, in the county of Whatcom and Stateof Washington, have invented certain new and useful Improvements inSaw-Sets, of which the following is a specification.

This invention relates to means for setting the teeth of saws todifferent positions or angles with relation to the saw body.

An object of this invention is to provide means for bending or settingthe cutting edges of saw teeth to give the same a proper set, meansbeing provided for determining when the tooth has been set to the properposition, and means being furthermore provided for affording a ready andexpeditious disengagement of the said mechanism from the saw tooth.

A still further object of this invention is to provide a sawset having aplunger and means associated therewith for setting a saw tooth, meansbeing provided for retaining the plunger and the means associated withit in operative relation while the mechanism is being manipulated.

With the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this specification wherein likecharacters denote corresponding parts in the several views, and in whicFigure 1 illustrates a View in elevation of a fragment of a saw with thesaw setting device embodying the invention applied thereto; Fig. 2illustrates a vertical sectional view through the lower portion of thesetting mechanism; Fig. 3 illustrates a sectional view on the line 8*?)of Fig. l omitting the teeth on each side of the one to which thesetting device is applied; Fig. 4 illustrates a perspective View of ahousing associated with the plunger; and Fig. 5 illustrates aperspective View of an antifriction roller to be used in connection withthe plunger.

In these drawings 6 denotes a plunger having a recess 7 in one sidethereof, the all of which forms a cam by reason of the fact that thesaid well extends inwardly and outwardly and terminates in a shoulder 8,the same forming a seat for a roller 9 which roller is intended to rideover the cam or inclined surface formed in the manner just stated.

The plunger 6 has a set screw 10 threaded into it, which set screw isdesigned to limit the movement of the housing with respect tothe'plunger or vice versa.

The housing to which reference has been made is identified by thereference numeral 11 and is shown as of restricted area at the topascompared with the area of the bottom, thatis to say, there is an offset12 at one side of the said housing and the wall at the opposite'side isremoved in part, the said housing having lugs 13 extending toward eachother and forming with the rear and side walls a restricted channelcoextensive in area with the cross sectional area of the plunger,itbeing understoodthat the space 14 at the lower portion of the housingis designed for the purpose of receiving a tooth of a saw which is to beoperated on by the plunger, roller and housing, when movement of onewith relation to the other is effected.

The rear wall of the housing has a screw 15 which screw is provided forthe purpose of adjusting the housing with relation to the plunger. Whenthe said screw is moved to enter the housing, it bears against onesurface of the plunger and draws the opposite wall of the housing towardthe front of the plunger so that the roller is retained in the seal ofthe plunger and the roller serves to prevent disengagement of thehousing from the plunger.

The rear surface of the front wall 16 of the housing is beveled to forma clearance for the tooth which is to be bent by the action of the sawsetting mechanism and the rear surface of the front wall 16 is furtherprovided with bearing surfaces 17 on which the ends of the roller 9 ridewhen there is movement of the plunger with relation to the housing; thusthe roller is caused to engage the camsurface of the plunger and thebearing surfaces with the housing when the maximum set of which themechanism is capable is imparted to the tooth.

I claim 1. In a saw set, a housing having plunger slidable in thehousing and guided by the lugs, said plunger having a recess with abeveled wall, a portion of the housing extending beyond the lugs andhaving lugs, a

a wall, the inner side of which is beveled, and a roller fitting in therecesses of the lunger and coacting with the beveled inner Wall of thehousing to set saw teeth.

2. In a saw set, a housing, a portion of which is of increased crosssectional area at its lower end, the inner side of one wall of thelarger portion being beveled, roller engaging ribs on the inner side ofthe beveled Wall, a plunger in the housing having a re cess with abeveled wall, a roller seated in the said recess and adapted to coactwith the wall of the housing for setting saw teeth, and means forlimiting the movement of the plunger with relation to the housing.

3. In a saw set, a housing, a portion of which is of increased crosssectional area at its lower end, the inner side of one Wall of thelarger portion being beveled, roller engaging ribs on the inner side ofthe beveled wall, a plunger having a recess with a beveled Wall, aroller seated in the said recess and adapted to coact with the Wall ofthe housing for setting saw teeth.

4. In a saw set, a housing, a portion of which is of increased crosssectional area at its lower end, the inner side of one wall of thelarger portion being beveled, roller engaging ribs on the inner side ofthe beveled wall, a plunger having a recess with a beveled wall, aroller seated in the said recess and adapted to coact with the wall ofthe housing for setting saw teeth, and means adjustable in the housingfor engaging the plunger to hold the housing, roller and plunger inassembled relation.

5. In a saw set, a housing, a portion of which is of increased crosssectional area at its lower end, the inner side of one Wall of thelarger portion being beveled, roller engaging ribs on the inner side ofthe beveled wall, a plunger slidable in the housing having a recess witha beveled wall a roller seated in the said recess and adapted to coactwith the wall of the housing for setting saw teeth, means for limitingthe movement of the plunger with relation to the housing, and meansadjustable in the housing for engaging the plunger to hold the housing,roller and plunger in assembled relation.

In testimony whereof, I hereunto aflix my signature in the presence oftwo Witnesses.

CHARLES E. MILLER.
